So far I have traced the cause of the problem to something near the
following log entries: I really want to know exactly *where* in the
source the process is failing. Currently the abort message gets
triggered with:

[abort] Checking line 0
[abort] Abort failure for line 0

I assume this is an error and that the abort message should state
where in the source the failure occurred: line zero doesn't seem
likely! ;-)

My assumption is that something bad occurs when creating the
directory, I'd like to find out why. I can make the directory fine
on the command line, so it's not a length or other file limitation.

Can anyone suggest how I can track this down. This relates to the
following bug:
